Connect Multiple PhoneTree Hardware Units
If you are attempting to connect multiple PhoneTree units to your computer and do not have the necessary USB ports available, purchase and install a true dual (or quad) host controller card instead of using an external USB Hub. This will help to ensure each PhoneTree unit receives the correct amount of USB bandwidth. When connecting your PhoneTree hardware, please limit 1 unit per USB port and no more than 24 lines per single host controller. If you need assistance determining your computer's current USB capabilities, please contact PhoneTree Customer Support.
